4.2 COMMUNICATIONS WITH THE MILLENNIUM-GLONASS
GPSCARD
Communication with the MiLLennium-GLONASS GPSCard is straightforward, and consists of issuing commands
through the COM1 or COM2 port from an external serial communications device. This could be either a terminal
or an IBM-compatible PC that is directly connected to a MiLLennium-GLONASS GPSCard serial port using a null
modem cable. For specific information about any of the GPSCard commands and logs, please consult the
MiLLennium Command Descriptions Manual.
